# 1RM Max Calculator vs Workout Notebook

The clearest difference is review sentiment: 1RM Max Calculator at 70% against Workout Notebook's 0%. 1RM Max Calculator also leads on ads (none vs shown) and ratings volume (22 vs 5). Workout Notebook's advantage is rating (4.8 vs 4.2) and update cadence (every 2 weeks vs every 6 weeks). On price, in-app purchases and monetization model there is nothing between them.

Both are free to download. 1RM Max Calculator sells 3 one-off in-app purchases and Workout Notebook sells 3 in-app purchases, starting at $1.99 per month. Whichever you choose, the download price is not the number that matters.

Workout Notebook holds the better App Store score, 4.8 against 4.2. Both are backed by a comparable volume of ratings — 22 and 5 respectively. Written reviews complicate that: 70% of 1RM Max Calculator's written reviews are positive against 0% of Workout Notebook's, so the app with the better star average is not the one people write more warmly about.

1RM Max Calculator ships an update every 6 weeks, Workout Notebook every 2 weeks. The most recent releases landed on November 2, 2026 and November 3, 2026 respectively.
